o BoNHAM,rEXAs The Schedule referred to in these Letters Patent and making part ofthe same To all whom it may concern i a Be it known that I, Zaonaumn B. Sins, of Ron ham,,m the county of Fanniu and State of Texas,

a have invented a new and useful Improvemcntin Two-- Horse Equalizers; and I do hereby declare the followmg to be a clear'andexact description of the.

nature thereof, suflicient to enable others skilled 'in the art to which myiuvention-appertains to make and "use the same, reference being had to the accompanyiug drawing. in which the figure is a top or plan view a My invention is an improvement, in the. class of equalizers adapted fordtwo horses,.as will he hereinutter more fully described. i

In the drawing 1 A represents a double-tree, and B B, single or whiffletrees.

The connection between the said douhleand whit 'hetrecs is as follows: i

. A series of longitudinal openings, 0: G, is made in the double-tree, and into these openings are inserted the bolts 1),,wnan carry hooks, eyes, or rings,

from which whiflletrees are hung.

It will be seen that the whifflet-rees may readily be brought nearer together orseparatedfrom each other bysimply moving the bolts and introducing them into the relative opening in the double-tree.

E E are stretcher-loops, which are connected to the double-trees and to the plow-beam'or plow-clevis.

These stretchers may be adjusted to increase or decrease the leverage of the double-trees by means of openings F F in the double-trees. The operation is as follows:

When the animals are of about equal strength, the

bolts carrying the hook-eyes are adjusted in the openings formed in the double bar, at equal distances .from its ends, the stretcher irons remaining in either the center or outer holes of the double bar, the equalization thus being perfect; but, if the animals should be of unequal strength, either of-the bolts carrying the hook-eyes may be moved inwardly, or one arm of the stretcher-chains or irons may be adjusted inwardly, thus allowing each animal to perform its proper share of the work, and preventing the constant jerking which is a common occurrence in single-trees aml double vans heretofore in use,

Having thus described my invention,

What I claim as new, and desire to secure by Let ters Pateut, is' p The double-tree A, provided within. series of longitudinal openings, 0 G O, and the openings F 11, as

described, when combined and operating in connec tion with the stretcher-loops E E andwhiflletrees B B, substantially as set forth;

The above signed by me this 11th day ofFeh ru-i ary, 1870.-
